UTIL_BubbleTrail is a UTIL provided in the Source code for a trail of bubbles.
Usage
//-----------------------------------------------------------------------------
// Purpose:
//
// Input : Vector &from | Where the bubble trail should emit from
// Input : Vector &to | Where the bubble trail should go
// Input : int - count | How many bubbles
// Output :
//-----------------------------------------------------------------------------
void UTIL_BubbleTrail( const Vector& from, const Vector& to, int count );
Examples
//-----------------------------------------------------------------------------
// Think every 0.1 seconds to make bubbles if we're flying through water.
//-----------------------------------------------------------------------------
void CHunterFlechette::BubbleThink()
{
//What this does is think every 0.1 seconds, and checks if the Flechette is in water.
//If it's not in the water, it exits the function and checks again in 0.1s.
//If it is in the water, then it creates a bubble trail every 0.1s.
//SetNextThink having two params has something to do with SetContextThink.
SetNextThink( gpGlobals->curtime + 0.1f, s_szHunterFlechetteBubbles );
//If it's not in the water, just check again in 0.1s.
if ( GetWaterLevel() == 0 )
return;
//Create a bubble trail, starting at the Origin-Velocity, so
//the origin - 0.1 it's velocity, or behind the Flechette
//The bubbles will head towards it's actual origin, like they were pulled
//forward by it's movement through the water.
UTIL_BubbleTrail( GetAbsOrigin() - GetAbsVelocity() * 0.1f, GetAbsOrigin(), 5 );
}
